The techniques of field operations influence the crop stand and yield greatly. These factors operate largely through their influence upon soil physical properties and plant growth. The principal cultural operations adopted during cane growth period are as follows:
(a) Interculturing:Interculturing with the help of 5 tyne cultivator should be done after 45 days after planting.
(b) Detrashing:Detrashing of dry leaves may be done to avoid sprouting of buds due to accumulation of water within the leaf sheath.
(c) Removal of off types: Removal of mixture and diseased clumps must be ensured for healthy seed cane production.
(d) Earthing–up:Earthing-up should be done in the last week of June with the help of Bihar senior ridger to provide anchorage to plants and also to provide sufficient drainage for removal of excess water. It also suppresses late formed tillers or water shoots as it is a parasitic in nature. At this stage, the remaining 25 per cent dose of nitrogen along with carbofuran 3 G (insecticide) @ 33 kg/ha may also be applied to support the cane during grand growth period.
(e) Propping: To prevent lodging of cane, propping may be done in the month of August-September by trash-twist method. In this method two adjacent rows of cane brought together to form a sort of arch and the lowest leaves of cane were twisted in to the form of rope.
